Comfort is not to be taken lightly. The nicest driving car I ever owned was my 2001 E38 (740iL). I loved driving that car and it made me smile every time I parked it and looked back while walking away. I heard two much younger guys talking in a bar one night about the awesome bimmer sitting out front and then realized they were talking about my E38. Style and comfort couldn't overcome the maintenance nightmares, though. If I made it through a month without a repair bill I felt blessed.
I still think about going back to a 7-Series. If you like the way the F10 drives, you'll love the F01.
